he mentions general petraeus, jennifer. then-senator obama wasn't too convinced that the surge was going to work in iraq, that's the thing that general petraeus put together there. what's it like, the relationship between general petraeus and president obama now? >> reporter: well, you remember, jon, that in those september 2007 hearings after the surge had been going on for a few months it was a very intense exchange between then-senator obama who was campaigning for president. he didn't actually let petraeus answer a question. he simply used his time to speak and speak out against the iraq surge. it's rather ironic that now he is depending on the same general for almost exactly the same strategy in afghanistan, an afghan surge. and from what we understand, the relationship is very strong, and he is completely reliant on general petraeus who, as you know, is the third general in the last two years to be placed out there. so president obama really has to rely on him right now, and these elections tomorrow are very important
